Syon Abbey
King Henry V laid the first stone of Syon Abbey on the 22nd of February 1415. He stood before Richard Clifford, Bishop of London, to mark this moment in history. This act was not merely a pious gesture but part of a grand political strategy known as "The King's Great Work." Henry V sought to rebuild Sheen Palace and establish three monasteries nearby to solidify his dynasty's legitimacy. His father, Henry IV, had made a vow to found three monasteries to expiate guilt over the murder of Richard II. That vow remained unfulfilled until Henry V decided to execute it himself.
The original site lay in Twickenham Parish, directly across the River Thames from the royal manor of Sheen. The charter specified dimensions for the plot, describing a trapezoid with its longest side fronting the river. The foundation included a monastery of Celestine Order monks who were quickly dissolved due to their refusal to pray for the king during his wars with France. Another house, the Carthusian Sheen Priory, was built within Sheen Manor itself. These three institutions formed a multi-campus building scheme centered on the reconstruction of the palace.
Henry V chose the Bridgettine Order specifically because they offered a unique dual-gender structure that aligned with his vision of peace and tranquility. The order had been brought to England by Henry Lord FitzHugh, who suggested granting one of the planned foundations to them. This decision set Syon apart from other religious houses of the time. The first stone laid in 1415 marked the beginning of a complex architectural and spiritual experiment designed to serve both political and dynastic ends.
The full complement of Syon Abbey consisted of exactly 85 persons divided into two distinct groups. Sixty women lived as nuns under the leadership of an abbess, while twenty-five men served as priests, deacons, and lay brethren. The Bridgettine rule mandated that these sexes dwell in separate habitations within the same monastery. The legal corporate entity was known as "The Abbess and Convent," which could transact business using a single corporate seal.
Women included one abbess and fifty-nine nuns. Men comprised one confessor general, twelve priests, four deacons, and eight lay brethren. Different sexes were required to live in separate courts, yet they shared the same monastic community. The Abbess acted as the overall presiding officer for the entire institution. Only eight abbesses were ever elected during the abbey's existence before its dissolution.
Matilda Newton served as titular abbess from 1418 to 1420. Joan North held the position from 1420 until 1433. Maud Muston led the community from 1433 to 1447. Margaret Ashby served between 1448 and 1456. Elizabeth Muston remained in office from 1456 to 1497. Elizabeth Gibbs took over from 1497 to 1518. Constance Browne governed briefly from 1518 to 1520. Agnes Jordan became the last pre-reformation abbess in 1520 and died on the 29th of January 1546.
The Bridgettine order was a modified version of St Augustine's rule with particular devotions to the Passion of Christ and the honor of the Virgin Mary. Saint Bridget herself was a visionary who reportedly saw the Risen Christ displaying his wounds. The nuns sent by Abbess Gerdeka Hartlevsdotter from Vadstena Abbey in Sweden included Anna Karlsdotter, Christina Finwitsdotter, Christina Esbjörnsdotter, and Anna Esbjörnsdotter.
Sometime before 1431, the Abbess and Convent received permission from King Henry VI to move the monastery downstream. They chose a new site within Isleworth parish, approximately one mile and a half from their original location. This land had been in the monastery's ownership since 1422 when an act of Parliament separated the manor of Isleworth from the Duchy of Cornwall and gave it to Syon. The reason for the move was to gain more space and avoid potential spiritual dangers caused by too close intermingling of the sexes at the original Twickenham site.
Letters patent ratified by the king dated 1431 made clear that some buildings were already completed while others remained unfinished. It seems living quarters or "mansion" must have started several years before 1431 to be described as complete in official documents. However, another building, possibly the new church itself, still had not been finished eleven years later by 1442. Henry VI issued further letters patent granting special privileges for transporting building materials from the royal manor of Sheen across the river to Isleworth.
Archaeological work suggests the new site lies partly underneath and to the east of the present Georgian mansion of Syon House. Foundations of the Monastery Church were partially uncovered starting in summer 2003 during Channel 4's Time Team archaeological programme broadcast on the 4th of January 2004. Medieval masonry blocks found in the foundation wall of the north wing provided evidence that the west end of the church may have been incorporated into the current house built by Protector Somerset.
Following Henry VIII's decision in 1534 to break with Rome, many residents of Syon expressed favorable views toward the King's supremacy over the English Church. Some even converted recalcitrant monks from other monasteries to accept this new status. Yet many refused to acknowledge the King's title as Supreme Head of the Church. Thomas Cromwell visited Syon personally to obtain expressions of acceptance but met an antagonistic reception at the front-door grate.
One monk named Richard Reynolds facilitated a meeting between Sir Thomas More and Elizabeth Barton, the mystic known as the Holy Maid of Kent. This gathering fueled opposition to the King's divorce and remarriage. Cromwell sent agents Thomas Bedyll and Master Leightone to secure required acceptances from nuns and monks. Bedyll reported that "the bretherne stand stif in thaire obstinacy." Two were sent to the Bishop of London for conversion while two Church of England clerics attempted to convert Whitford and Little without success.
On the 4th of May 1535 Reynolds was hanged, drawn and quartered at Tyburn for denying the king's supremacy. His martyrdom later gained him canonization from Rome. The monastery finally surrendered to the king's commissioners in 1539 when the community was expelled. Annual net revenues were then reported to be £1,731. A very large pension of £200 was given to Abbess Agnes Jordan while junior nuns received £6 each. The male Confessor-General received a pension of £15 and junior monks received £6 to £8 each.
The expelled community did not disband but instead exiled itself to the Netherlands. These nuns included Elizabeth Sander and Katherine Palmer who would later visit England on missions. The community was briefly recalled following the accession of Queen Mary I in 1553 when the Abbey was reestablished by a charter issued on the 1st of March 1557 by Cardinal Pole. Katherine Palmer was elected abbess on the 31st of July 1557 supported by Queen Mary. The buildings had remained intact during this interval.
Upon the accession of Protestant Queen Elizabeth I in 1558, the Religious Houses Act 1558 annexed and redissolved certain religious houses including Syon. Nuns obtained royal license to leave England eventually settling in Lisbon, Portugal where they arrived in 1594 after experiencing many troubles traveling through France and Spain. While in Lisbon they produced an illuminated petition to the King of Spain and his daughter asking for help returning to England. This document called the Arundel Manuscript is now housed at Arundel Castle.
The Lisbon years represented a period of survival despite political upheaval across Europe. The community maintained their identity and spiritual practices even while displaced from their original home. Their ability to preserve their traditions abroad demonstrated remarkable resilience in the face of repeated dissolutions and forced migrations.
The Lisbon community returned to England in 1861 settling first in Spetisbury, Dorset. They moved in 1887 to Chudleigh, Devon occupying a building known as Chudleigh Abbey. Then in 1925 or possibly 1935 they relocated to Marley House in Rattery parish, South Brent, Devon. The religious community thus became the only English one that survived the Reformation unbroken until its final closure.
A large piece of sculptured stonework from the monastery's remains was returned ceremoniously by the Duke of Northumberland who owned Syon House. In 2004 remaining medieval books were deposited for safekeeping with University of Exeter Library. By 2011 Syon Abbey had been reduced to three elderly sisters and was closed and sold. Remaining sisters now live in Plymouth where they continue their spiritual life.
Marley House was renamed "Syon Abbey" in 1925 when the community took up residence there. Walter Palk built this Georgian mansion between 1742 and 1819 while serving as Member of Parliament. The site represents a continuous thread connecting the original foundation to modern times despite centuries of political and religious turmoil.
Foundations of the Monastery Church lying to immediate east of Syon House were partially uncovered starting summer 2003 during Channel 4's Time Team archaeological programme broadcast on the 4th of January 2004. Programme highlighted medieval masonry blocks in foundation wall of north wing as evidence west end church may have been incorporated into current house built by Protector Somerset. Subsequent sweeping floor demonstrated Tudor floor surface continued underneath wall suggesting medieval blocks simply reused when wing rebuilt in 1820.
